UREA AMMONIUM NITRATE (UAN) 32%
|
The UREA/AMMONIUM NITRATE (UAN) solution is created by dissolution of the amide and nitrate salt in water. It may have a slight ammonia odor. Approximately 35% UREA blended with 45% AMMONIUM NITRATE makes a fertilizer solution that is 32% nitrogen by weight.

APPLICATION RECOMMENDATIONS
• The lowest salt-out temperature possible for UAN 32 is 32oF at a ratio of 1.30 AMMONIUM NITRATE to UREA.
• UREA is used as a slow release fertilizer. It must be decomposed by microorganisms before it can be assimilated by plants. The AMMONIUM NITRATE is the fast release part of the fertilizer. The plants quickly absorb the nitrate ion and ammonium ion for immediate metabolism.
• Consult your local fertilizer dealer for application recommendations
TRANSPORTATION, STORAGE AND HANDLING
• The transport of UAN does not require a DOT placard
• UREA/AMMONIUM NITRATE solution will decompose into ammonia, carbon dioxide and nitric acid at 237oF
• ALWAYS wash vessels containing UAN thoroughly before attempting repairs requiring welding
• ALWAYS restrict it from the drainage Should a large spill of UAN solution occur.
• The high nitrogen content (32%) will kill foliage if not diluted
• UAN can be handled by the municipal water treatment facility if spilled in a municipality
